Corrosion is a significant problem for underwater structures, particularly in environments where there are conditions that accelerate corrosion such as stray electrical currents. The New York Power Authority (NYPA) is concerned about corrosion on the

As economic pressure builds to fully utilize the capacity of existing power equipment, dynamic rating systems allow for informed decisions about circuit load limits. Dynamic thermal ratings offer a way to increase capacity under most weather- and loa

A 345 kV self-contained fluid-filled cable circuit was installed in an environment where corrosion of the armor may occur. To better understand the conditions that may result in corrosion, stray currents in the cable end zones and in the middle (subm

The coefficient of friction between the pulling rope and cable pipe for a high-pressure fluid-filled cable was determined in order to characterize the effects of pulling tension and sidewall pressure on this parameter. Pipe wear was also measured. Th

Steps taken by one utility to obtain substantial increases in power transfer capability for an existing 115 kV pipe-type cable circuit are summarized, and tests and analyses that were done to verify that the cable could achieve the new ampacity are d

An underground pipe-type cable system is represented by a thermal impedance network. A ladder network of resistances/capacitances represents the cable out to the outer surface of the pipe. The earth, adjacent pipe-type cables, and cable images are mo

Interests in magnetic fields over the last 15 years have been a transient issue, but general utility guidelines are to practice prudent avoidance where possible. This paper discusses various design issues considered by a utility preparing to undergro

Ampacities of two 115 kV high-pressure gas-filled (HPGF) pipe-type cables in Bridgeport, Connecticut are limited by a portion of the circuit that crosses under the Pequonnock river. The installation conditions, soil thermal parameters and circuit loa
